In this guide we show you how to block mould and mildew stains permanently whilst achieving a decorative finish.
All surfaces must be clean, dry and free from anything that will interfere with the adhesion of the materials to be applied. Remove loose and failing material by scraping or brushing with a stiff bristle brush to a sound edge. Feather sound edges with a fine grade abrasive paper. In areas with remaining sound paint clean down with Zinsser Universal Cleaner & Degreaser to remove any contaminants. Rinse thoroughly with clean water to remove all residues. Allow to dry. Fill any cracks and small surface defects with a suitable filler as appropriate in accordance with the manufacturer’s instructions. Allow to dry. Rub down with a fine grade abrasive paper. Remove all dust. Remove all visible signs of organic growth and treat the areas with Zinsser Mould Killer & Remover in accordance with the manufacturer’s instructions. Allow to dry.
Prime all stained, bare and filled areas with one coat of B-I-N® Primer Sealer in accordance with the manufacturer’s instructions. For a water-based alternative apply B-I-N® AQUA Primer Sealer. Allow a minimum drying time of 45 minutes in normal drying conditions.
Decorate with two full coats of the mould-resistant PermaWhite® Interior Matt or Satin in accordance with the manufacturer’s instructions. Allow a minimum drying time of two hours between coats.
